206FR c  1968Va04: produced by {+197}Au({+20}Ne,X) reaction at 145-153 MeV. At
206FR2c  lower energies, and for other reactions, the |a line of {+210}Ac is
206FR3c  contaminated with that for the {+211}Ac isotope
206FR c  2000He17: Produced using various heavy-ion reactions at GSI. The
206FR2c  velocity filter SHIP was used to separate reaction residues and
206FR3c  scattered beam. 16 strips position sensitive silicon detector was
206FR4c  used to implant the recoils and correlate subsequent alpha decay
206FR5c  events
